Hi, In a libvirt/KVM setup, what is the best way to prevent untrusted guest machines from (a) sending packets with a sender address different from their own and (b) reading packets not intended for them? Note that guests may have any number of IP addresses they are allowed to use legitimately. Guido -- Too much multitasking isn't good for you.

I'm trying to have a go at CLI spoofing. My outbound calls may go out over various VoIP providers, using least cost routing to determine which provider for call destination and time of day. No matter which provider I go out over, i'd like the called party to only see only one of my numbers - that number will be the only number i'll want people to call back on. To test, i've

Hello all. I know this does not directly relay to Ethernet bridging but I need some advise... anyone want to give me some info/help on the subject. In the interest of multipath routing I need to know if it is possible to do a one-way arp spoof. Lets start with the machines layout... br1------ADSL br2------cisco router-----serial line. br0-----Internal network. I already have

Hi all Assume that you have a linux bridge with two interfaces eth0 and eth1 enslaved to this bridge What is the difference between sniffing the bridge and sniffing its interfaces? tcpdump -i br0 vs tcpdump -i eth0 Thanks MiniME -------------- next part -------------- An HTML attachment was scrubbed... URL:

I can think of several potential differences. ?You may miss any bridge specific traffic (STP, LLDP) using the interfaces generated by the bridge itself. If you have vlan tagged sub interfaces you might also miss that traffic if you were snooping a particular interface. Obviously you will miss any on-wire broadcast traffic specific to the layer1 connection a particular interface was connected to

Is there anyway to "spoof" a BLF signal to a phone from within a dialplan? That being so I can turn a BLF light on or off on a phone when a certain thing happens in a dialplan?

Hello everybody! I am having the following problem and since I am a beginner in playing with asterisk, i can't solve it: I am trying to integrate my existing H.323 network in real world telephony by ISDN cards. The problem is that i DON'T want to change all e164 numbers in my h.323 network and my ISDN provider doesn't accept those identities (CIDs). So, i have to spoof the outgoing

Anyone running caller id spoofing applications in the USA running asterisk?

I have an idea for a protocol extension to limit the exposure of the complex crypto code in ssh servers. It's like tcp-wrappers, but based on a secret token rather than IP address. Patch against openssh-3.7.1p2: http://nick.cleaton.net/openssh-cc-0.03.patch Details ======= The "Connection Cookies" mechanism is an unofficial ssh protocol extension designed to prevent attackers

Ok assuming I don't want to record calls using * but instead want a dedicated server that listens to a mirror port and records calls. Is there a cheap software package out there for doing this for mgcp/sccp? I know if evern cut over to * there is a way but I doubt I will even cut 100% over to * so I was wonder what the list has heard of for call recording via sniffing my gates. I know there

Hi, I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own subnet: 192.168.1.x and 192.168.0.x. All DomUs can talk to each other OK through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2 The scenario: I''m trying to capture packets on Dom2 on 192.168.0.x from external devices that are sending SIP stuff to Dom1, but fail to capture any packets. I

Hello, I am trying to understand how Tor protect to ISP sniffing in proxy. I suppose this steps: 1) Dowload Tor software, software should signed or downloaded from SSL site. 2) Computer software verify that software is not modified, and install it. 3) Vidalia starts tunnel, At this point how keys are exchanged? ... -- -- Devel in Precio http://www.pas-world.com

https://bugzilla.samba.org/show_bug.cgi?id=10977 Bug ID: 10977 Summary: Rsync path spoofing attack vulnerability (rsync 3.1.1 tested) Product: rsync Version: 3.1.1 Hardware: All OS: Linux Status: NEW Severity: critical Priority: P5 Component: core

I am currently suffering various SIP attacks. I am using the following extension to record the caller's IP address: exten => h,n,set(CDR(srcip)=${CHANNEL(recvip)}) However, in recent attacks, this IP address is not correct, and I believe that they are spoofing it. I am using asterisk 1.6.2.15. Does the CHANNEL(recvip) variable record IP show in the SIP header instead of the real, UDP

Hi there. I have configured kvm domain (rhel6.4) with ethernet bridged over macvtap, and found no filtration applied except mac. 'virsh' just silently ignoring attributes 'filterref' and 'ip address' in different formats. No error on validate stage. Config examples: ... <interface type='direct'> <mac address='52:54:00:31:ae:1a'/>

Hi All, I have a program that does ARP spoofing (not for hacking purposes!), and I experienced occasional crashes in my switch (Cisco UBR7200). Does anyone else had a similar problem? Maybe with other switches/routers? Can this be the results of two machines trying to register the same IP? Send invalid ARP packets? Thanks, Yuval.
